i 011. BURNER.

Application filed December 12, 1925.

The invention relates to burners, and more particularly to the type ofburners for utilizing a hydrocarbon fuel which is atomized by a fluidand vaporized by heat, the fluid mixing with the vaporized fuel toproduce a gaseous mixture which burns with an intense heat, the flamebeing utilized in the industrial arts for Various purposes.

The invention provides a burner, embodyinga casing having an elongatedoutlet at one end and an inlet at the opposite end for steam or otherfluid, and a tube within j the casing terminating at one end adjacentthe outlet thereof vand connected at its opposite end with a source ofoil supply, the tube being adjustable laterally at its outlet end withreference to the outlet of the casing to controlthe amount of fueldelivered in a given time.

l/Vhile the drawings illustrate a preferred embodiment of the inventionit is to be understood that in adapting the means to meet specific needsand requirements the design may be varied, and such other changes in Vthe minor details of constructiony may be resorted to within the scopeof the invention as claimed, without departing from the spirit thereof.y

For a full understanding of the invention and the merits thereof,reference is to be had to the 'following description and the drawingshereto attached, in which,-

Figure 1 is a top plan view of an oil burner embodyingthe invention, aportion of the header at the receiving end being broken away, p

`Figure 2 isa vertical, central, longitudinal, sectional view on theline 3 3 of Figure 1,

Figure 3 is a front view of the burner, and

Figure 11 is a detail sectional view of the delivery end of the burneron the line L1---4 of Figure 2. Y

Corresponding and like parts are referred to in the followingdescription and designated in the several views of the drawings by likereference characters.

The burner comprises a casing 1 of tubular form and is enlarged at oneend t-o provide a polygonal portion 2 for the reception of a wrench orSpanner, an outer flange 3,

outlet and, as shown most clearly in Figure 2, one end of the elongatedoutlet G termi nates in line with the inner wall of the casing whereasthe opposite end terminates a short distance from the adjacent portionof the inner wall leaving a curved shoulder 7 which constitutes adeiiector to direct the steam or other fluid medium upwardly through theoutlet 6 whereby to control the delivery of the fuel and the heat. Theheader is subdivided by a partition 8 to form chambers 9 and 10, thechambers 9 being in communication with the inner end of the casing 1whereas the chamber 10 is adapted to be connected in any preferred waywith a source of fuel supply. A fluid medium, such as steam, is suppliedto the chamber 9 in any determinate way by means of a pipe 11 and suchfluid passes through they casing 1 and discharges through the elongatedoutlet 6.

A tube 12 is disposed within the casing 1 and its external diameter isless than the diameter of the bore, or opening of the casing, so as toleave a surrounding space 17 between the tube 12 and the casing 1 forthel passage of the steam or other fluid. The tube 12 is supported atone end in the partition S and its opposite end terminates adjacent theelongated outlet 6 and the curved deflecting shoulder 7 and isadjustable laterally by means of a set screw 13 threaded in to a side ofthe casing 1. rlhe delivery end of the tube 12 is tapered andconstricted, as indicated at 1li, to provide a reduced outlet. Liquidfuel from a suitable source of supply is fed to the chamber by means ofa pipe 15 which may connect with the header at any determinate point. Asshown, two pipes 15 are provided and one may be closed or connected to asource of steam supply for cleaning the tube 12 when required byshutting ofi' the oil and admitting steam into the chamber 10. Anopening is formed in the outer end of the header in line with the tube12 and is closed by means of a plug 16 and this opening admits ofcleaning the tube by means of a wire when the accumulation cannot beremoved by a blast of steam through the tube.

In the operation of the burner, a fluid medium, such as steam, issupplied to the chamber 9 by means of the pipe 11 and passes through thecasing 1 and discharges at the outlet (i. Fuel supplied to the chamber10 enters the tube 12 and escapes through the outlet lll and eommingleswith the steam or other fluid, at the outlet 6, the resultan-t gaseousmiXture being consumed as it emerges from the outlet 6 producingr aflame of great intensity.

It is observed that the steam is forced. through the Casing l around thefuel tube 12, with the same pressure at the opening 14, the steam belowis given a greater or less volume by reason ot the raising or loweringof the outlet l-l. The raising of the outlet lll increases the volume ofsteam deflected from below by the curved detlecting shoulder 7 andthereby cuts oil' the flow` of oil, the volume ot' steam remaining thesame,

-but greater amount being degected from below.

It is tui-ther noted that the shape of the casing l at the opening G isrectangular ai: the top and circular at the bottom, thereby direct-ingthe liow of the steam horizontally at the top and upwardly and outwardlyat the bottom, thus causing the steam from below to be more greatlysaturated with oil than the steam from above, thereby producing athorough and complete mixing of the oil and steam, immediately as itpasses through the outlet 6 into the lire box, and the heat is equallydistributed over the entire lire box, thereby producing the highestdegree oiE elieiency and the highest consumption of the heat units fromthe fuel. To accomplish this, it is necessary that the outlet 6 be asindicated in Figure 3, viz: oblong in shape, the greater portionextending above the center of the casing l.

-As the oil leaves the outlet 14 it isy deflected upwardly into the mainblast ol." steam escaping throughy the outlet 6 by a very smallportion'of the blast which is 1diverted upwardly by the curvedldeflecting deflecting shoulder 7 cause an automatic diverting of the oilinto the main part of the blast but it also creates an automatic controlor' the lire as the steam pressure drops.

Having thus described the invention, I claim:

l. An oil burner comprising a casing having an elongated outletterminating at one end in line with the inner wall of the casing and.having its opposite end spaced some distance troni the adjacent innerwall of the casing, a fuel supplying tube within the easing having itsoutlet adjacent the elongated outlet ot the casing and means toradjusting. the delivery endy of the tube in the direction ot the lengthoi' the elongated outlet Ot the casing, whereby to regu-late thedischarge ot lthe fuel.

2.` An oil burner comprising a casing having an elongated outletterminating at one end in line with the inner wall of the casing andhaving` its opposite end spaced some distance from the adjacent innerWall of the casing and connected thereto by a curved detleetingshoulder, a fuel supplying tube within the casing` having itsv outletadjacent the elongated outlet and the inner` curved detlecting shoulderof the casing and means tor adjusting the delivery end of, the tube inthe direction ot' the lengthy of the elongated outlet of the casing,whereby to regulate the discharge of'. the' fuel.

3. Au oil burner comprising a header divided by a partition to formAchambers, one ot the chambers adapted tofreceivea fluid medium and thevother chamber being con,- nected with a source of liquid fuel. supply, acasing` connected. with the Huid receiving chamber and` having anelongated outlet, a tube within. the casing and supported in thepartition of the header and in communication with the fuel receivingchamber, and aset screw i-n a side'of thecarsing and adapted to adjustt-he delivery end ofthetube laterally to regulate the discharge oitv thefuel.

In testimony whereof I aliix my signature.
